CHANGE-MAKING DEVICE.

Specification of Letters Patent.

Patented July 12, 1910.

Application filed October 20, 1909. Serial No. 523,563.

To all whom it may concern:

Be it known that I, LOUIS J. DITTMAR, a citizen of the United States, residing at Louisville, county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Change-Making Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in change making devices and particularly shown in my Patent No. 920,281, dated May 4, 1909.

This invention has for an object to provide a novel and improved construction of means for controlling the delivery from a series of coin chutes so that the coins therein may be delivered from one or more thereof as desired.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawingsFigure l is a front elevation with the casing removed; Fig. 2 is a side elevation with the casing removed; Fig. 3 is a vertical section through the delivery controlling device; Fig. i is a front elevation thereof; Fig. 5 is a detail perspective of the means for retaining the coin delivery; and Fig. 6 is an elevation of the key to release the latch shown in Fig. 3.

Like numerals of reference refer to like parts in the several figures of the drawings. The numeral 10 designates a casing which may be of any desired material or configuration adapted to receive the mechanism carried thereby. This casing is provided with a series of coin delivery chutes 11, any desired number thereof bemg disposed so as to deliver at the front of the machine. For this purpose the chute is provided with an angularly disposed portion 12 at its front, above which a feed wheel 13 is disposed and provided with segmental sockets 14: adapted to separately receive 'the coins to be discharged from this chute. The series of wheels may be of any desired thickness in order to cooperate with one or more chutes, for instance as shown, one of the wheels is of suflicient width to cooperate with two chutes and the remaining wheels of such width as to cooperate with one chute each, thus requiring only three wheels to control the delivery from four coin chutes. These wheels are pivotally mounted upon a shaft 23 mounted in supports 15 carried by the chutes 12 and the rotation of all of the wheels is controlled by a unitary retaining device 16 pivotally mounted at the front of the casing by means of arms 2a. This retaining device is provided with a standard 17 having at its upper end an angular portion 1.8 which carries a dog 19 disposed parallel with the shaft 23 so as to contact with the uppe'r surfaces of the wheels thereon. Extending rearwardly from the retaining device is an arm 22 which is disposed within the bifurcated lower end of the coin chute 21. This chute is formed with a communicating discharge chute 25 provided at its lower end with an alarm device 26 adapted to receive coins of an improper size and other articles which may be introduced in an attempt to operate the machine. This retaining device is normally held in raised position so that the body 16 thereof will contact with the lower portion of the wheels by means of a tension spring 27 extended from the portion 18 to a fixed part 28 carried by the casing as shown in Fig. 2.

For the purpose of preventing rotation of one or more of the wheels when released by the retaining device, a disk 30 is provided and pivotally mounted at 31 in the front of the casing by means of a tubular pivot 32 which carries an indicating disk 33. The controlling disk 30 is provided upon its inner face with a plurality of tangentially disposed ribs or flanges 3 1, these being of different lengths in order to control a corresponding number of the wheels 13 when brought into alinement therewith by a partial rotation of the disk. For the purpose of locking this controlling disk in its adjusted position, any desired means may be used, a convenient form thereof comprising a spring arm 35 secured to the casing at 36 and provided with a holding pin 37 adapted to enter any one of a series of apertures 38 within the controlling disk 30. These apertures are circumferentially disposed so that when the pin is released from one, it will automatically seat in the next aperture. For the purpose of releasing the pin, the lower end of the spring arm 35 has secured thereto a lug 39 disposed within the tubular pivot 32 of the controlling disk and adapted to be pushed inward by the insertion of a proper key 40 as shown in Fig. 6.

In the operation of the invention it will be seen that when the portion of the controlling disk having no flange thereon 1S opposite the delivery wheels, each of these wheels is free to rotate for a partial revolution when released by the movement of the retaining device due to the contact of a coin with the operating arm thereof. The downward movement of this arm withdraws the body of the retaining device from contact with the under face of the wheels and brings the dog into engagement with the upper face thereof. As soon as the coin is discharged by gravity from this operating arm, the retaining device is raised by lts spring to withdraw the dog from the wheel which permits the partial rotation thereof to discharge a coin before engaging the body of the retaining device. Under these conditions if a coin be inserted in the ma chine, four coins of less denomination will be delivered in change. If it be desired to deliver only three coins, the shortest of the flanges upon the controlling disk is brought into alinement with one of the wheels, while if two coins are to be delivered, the next longer flange is brought into position. hen the longest flange is brought into alinement with the wheels, the rotation of all of them is stopped so that there is no delivery when released by the retaining device. The invention is adapted for use either alone or associated with an article delivery device to be operated therewith and the number and a1"angement of the chutes and delivery wheels may be varied to suit the conditions of use and for operation by coins of any denomination for the delivery of either change or other articles from the machine. I he construction permits a change of the delivery mechanism without access to the interior of the machine while the indicating disk will readily show the number of coins to be discharged upon the insertion of a proper coin for that purpose. The controlling disk is locked in its adjusted position and cannot be released except by the insertion of a proper key for that purpose so that the machine cannot be readily tampered with to change the predetermined number of coins to be delivered therefrom. The invention therefore presents a simple efficient and economically constructed device for delivering a predetermined number of articles upon insertion of a proper coin therein.

Having described my invention and set forth its merits what I claim and desire to secure by Letters Patent is 1. In a change making device, the co1nbination with a series of delivery chutes, of independent feed devices cooperating with each chute, a unitary retaining device controlling all of said feed devices, means for operating said retaining device, and pivoted means having a plurality of members movable to control delivery from one or more of said chutes.
